Could be a failed sensor inside the recovery bottle.

Unplug the sensor. If the light goes out, the sensor is bad. HTH. -Jim

How do you unplug the sensor

Look for a black square gizmo on the plastic coolant recovery tank with a plug on it. Unplug it. If the light on the dash now is off, the sensor is bad. HTH. -Jim

I took the coolant recovery tank clear out and there is nothing but one hose hooked to it
